When I took out my loan with 705 FCU, I asked for a finance term of 48 months. I have been paying on my car loan for the last 36 months and I now have the money to pay off the rest of the payments. Will I be penalized for paying my loan off early?

No. There are no early repayment fees for paying the loan off early, and you will save money on the amount of interest you would have paid for the remaining 12 months of the finance term.
